@Adriatico
In terms of brightness, there is very little difference between the partially cloudy nights of OLCE1 and OLCE2. I've taken the screenshot you just posted (an OLCE1 shot) and put it side-by-side with an OLCE2 shot taken in the same cloud/sky conditions:
The one on the right is OLCE2.
@Myxale
I'm mot sure what you're asking about... what blending do you mean?
